In conclusion, we believe that culcium messenger system is involved in the regulation of pollen germination and pollen tube grwoth.

综上所述，我们认为钙信使系统积极参与了花粉萌发和花粉管生长的调控。

However, compared with pollen germination, pollen tube growth was relatively insensitive to verapamil and Co〓.

与花粉萌发相比，花粉管生长对Verapamil和Co〓相对不敏感。

Following characteristics of pollen germination and pollen tube growth were observed with fluorescence microscope.

用荧光显微镜对自交不亲和强度不同的梨品种丰水和菊水自花授粉及以丰水为母本的异花授粉后的花粉萌发及花粉管生长特性进行观察。

It is the first time that these phenomena were observed: Two nuclei are surrounded by plasma and locate at the central of the female gametophyte and the others nuclei are positioned at the fringe of the female gametophyte; Before the pollen tube enters the female gametophyte. the nuclei in chalazal end begin splitting of plasma and form multinuclear cell.4. The pollens of Gnetumc are spherical or applanate with single aperture. The ornamentation of exine is spine. The basis part of spine is lenience and the top part of spine is tip or obtuse sphere.

首次在买麻藤属植物的雌配子体中观察到2个游离核位于配子体的中央位置，且被一团原生质所包围的，其余的游离核位于边缘的现象以及花粉管进入雌配子体前，合点端的核已经发生胞质分裂形成多核细胞的现象 4、买麻藤的花粉近球形或扁平型，有单萌发孔，外壁表面具小刺状纹饰，小刺基部宽大，末端尖或钝圆。

Immunocytochemistry further revealed that the proteins encoded by these genes accumulated inthe elongating and condensing generative nucleus during development of bicellular pollen, and weremost abundant in the two sperm nuclei within an elongated pollen tube.

免疫细胞化学进一步显示，该编码的蛋白是由这些基因的累积inthe拔节和冷凝生成核的开发过程中bicellular花粉，并weremost丰富，在两个精子细胞核内的一个狭长花粉管。

Solid medium was using to study the effect of sugar, boron, calcium on pollen germination and pollen tube growth of Corylus heterophylla Farnch.× C. avellana L..

采用固体培养基研究了不同浓度的蔗糖、硼和钙配比对杂交榛花粉萌发及花粉管生长的影响。

In a compatible pollination, pollen germinates to extrude a tube that penetrates the stigma and grows extracellularly through the stylar tissues to ovules.

当花粉通过自交不亲合的筛选后，萌发的花粉管会穿透柱头并沿著花柱朝胚珠生长。

Method］ The process of flower opening and pollen tube germination of Lagerstroemia speciosa was observed and the pollen viability was determined through in vitro germination.［Result］ Sepals of L.
